Wood duck females often nest in tree cavities located in large-diameter deciduous trees. Temporal changes in forest age and composition during recent decades may have influenced the abundance of stems with suitable nesting cavities in the forested portion of Northern MN, United States. Thus, we ascertained whether temporal changes in the abundance of such stems occurred in this area during six Forest Inventory and Analysis (FIA) evaluation cycles (i.e., 1977 to 2015–2019). We used FIA data and independently estimated proportions of stems with suitable cavities in different tree-species, health-status, and diameter classes to estimate change in the abundance of such stems at three spatial scales. These spatial scales increased in areal extent from a study area to three ecological subsections to the Laurentian Mixed Forest ecological province. We used a Bayesian analytical approach to accommodate changes in FIA protocols among cycles. Both the abundance of stems with suitable cavities and an attribute associated with cavity occurrence changed during the analysis period, but findings were not entirely consistent among spatial scales. The estimated abundance of both suitable stems overall and those of late-successional tree species generally increased at all scales during the analysis period. Since 1990, increases in the abundance of health-impacted stems that were suitable for nesting occurred at all spatial scales. Our estimated densities of suitable stems during the 2005–2009 (1.20 [85% CrI: 1.04–1.39] suitable stems / ha) and 2015–2019 cycles (1.41 [85% CrI: 1.21–1.63] suitable stems / ha) were substantially greater than the <0.25 and 0.25–0.49 suitable stems / ha another study predicted would occur in Northern Minnesota during 2008 and 2018, respectively. Our results can inform forest management decisions and research directions for follow-up studies of nesting wood ducks.

“…Although some forest health data are collected on FIA plots (e.g. occurrence of damage-causing agents), these data are collected inconsistently and can be difficult to interpret 73 , 74 . Some of the difficulty arises from the panelized nature of the FIA sampling scheme: 20% or fewer of the plots are visited annually within each state (i.e.…”

Denser forests across the USA experience more damage from insects and pathogens

Forests across much of the United States are becoming denser. Trees growing in denser stands experience more competition for essential resources, which can make them more vulnerable to disturbances. Forest density can be expressed in terms of basal area, a metric that has been used to assess vulnerability of some forests to damage by certain insects or pathogens. A raster map of total tree basal area (TBA) for the conterminous United States was compared with annual (2000–2019) survey maps of forest damage due to insects and pathogens. Across each of four regions, median TBA was significantly higher within forest areas defoliated or killed by insects or pathogens than in areas without recorded damage. Therefore, TBA may serve as a regional-scale indicator of forest health and a first filter for identifying areas that merit finer-scale analysis of forest conditions.

“…Various tree damages have also occurred due to several environmental factors that influence it (Safe'i qand Upe 2022). Tree damage can be identified as the cause to provide valuable information so that it is possible to prevent or overcome the occurrence of further damage (Randolph et al 2021).…”

Community forest management usually applies agroforestry patterns because it is felt that they will provide more social, economic and ecological benefits. Optimal yields will be obtained if the community forest is healthy. It becomes an effort to prevent forest destruction at a low level through forest health, thereby ensuring the functions and benefits of managed community forests. One indicator of forest health is the amount of tree damage that occurs and the condition of the crown. The purpose of this report is to provide an overview of the vitality condition of agroforestry-patterned community forests and to serve as a reference for future decisions about the maintenance and development of these forests. This study was conducted in a community forest owned by members of the combined forest farmer groups Satria Rimba, Way Khilau District, Pesawaran Regency, Lampung Province, Indonesia. The method used is the Assessment of Forest Health Monitoring (FHM) method. The parameters of the vitality condition assessment consist of tree damage and crown condition. This study provides results that show there are 14 types of tree damage that attacked the trees that made up stands in community forests. The most common types of damage occurred based on the percentage of incidents, namely damaged leaves (25.29%), broken branches (24.41%) and open wounds (23.34%). assessment for damage to the tree based on the CLI value, namely in the high category (clusters 2, 3); moderate category (clusters 1, 5, 6); and low category (clusters 4, 7). Assessment of the crown condition based on the VCR value, namely in the categories of ‘high’ (clusters 4, 5, 6), ‘moderate’ (clusters 2, 7) and ‘low’ (clusters 1, 3).
